It happens to me quite often, too. The only thing related in the
non-debug messages is:

Jan  8 12:02:19 moneypenny dhclient[68091]: 5 bad IP checksums seen in 5 packets
Jan  8 12:02:49 moneypenny last message repeated 743054 times

Jan  8 12:51:44 moneypenny last message repeated 10037074 times

... which accounts for the CPU usage, I guess. I killed the "bad IP
checksums" messages, so it doesn't annoy my syslog anymore, but it of
course didn't fix the underlaying issue. 

I was looking at those packets with tcpdump once and didn't see anything
obvious/bad there.

And yes, I didn't have this problem with ISC client. And I surely use
different cable provider, than the original poster ;)
